A new review says eating more protein does not always mean better health, and the right amount depends on age, activity, and health.

Researchers at the University of Wisconsin-Madison found that too much protein may not be good for you, after looking at over 350 studies.

In fact, it could even shorten your life if you are not very active and get protein from certain sources.

One dietary change could help you live longer.

To change your diet, think about your activity level and the food you eat, experts say.

People are getting mixed messages from doctors and influencers, says Tanya Freirich, a registered dietitian.

Active people can still benefit from more protein, says the expert.

The message has been to eat more protein, says the expert.

But too much protein can harm your kidneys and bones, and affect how your body uses calcium.
